I have a Pentair Intelliflo that's about 2 years old. I run it 24/7 on 1400 rpm which has worked out very well so far. I live in SC so not brutally cold weather in the winter. I became very accustomed to how it sounded, which was very quiet at low RPM. It has now become quite a bit louder and I'm wondering if that's a sign that something is not right or will go out prematurely. Here is a video. I appreciate any feedback from those that know much more than I about the inner workings of these pumps.
Thanks!
Robert
